[Meteor Lake + Realtek ALC298? Samsung NP960XGK] Internal speakers silent on SOF; HDMI audio works #5628
Description
On Samsung Galaxy Book4 Pro (NP960XGK) with Meteor Lake-P HD Audio Controller and Realtek codec, PipeWire exposes Speaker/HDMI sinks under SOF, microphones work, HDMI audio works, but internal speakers are silent. ALSA mixers are unmuted, Auto-Mute disabled, and trying EAPD/pin widget enable via hda-verb does not restore speaker output. Legacy HDA (with SOF disabled) is untested/partial; HDMI is used as a workaround. Regression not confirmed; persists on latest Fedora kernel as of [date].
Hardware:
Laptop: Samsung Galaxy Book4 Pro 16 (NP960XGK) [adjust if different]
CPU/Platform: Intel Meteor Lake-P
Audio: Meteor Lake-P HD Audio Controller + Realtek codec (likely ALC298 family)
Display/audio over HDMI: working
Software:
Distro: Fedora 42
Kernel: uname -a: [paste]
SOF firmware/topology: sof-logger -l /lib/firmware/intel/sof/ or sof-info output [see “Data to attach”]
PipeWire: 1.4.9
WirePlumber: 1.4.9
ALSA utils: 1.2.14
Observed behavior:
wpctl status shows Speaker and HDMI sinks; selecting Speaker produces no sound in any app.
HDMI sink plays audio normally.
ALSA controls:
Auto-Mute Mode: Disabled
Speaker: 100% unmuted
hda-verb attempts:
hda-verb /dev/snd/hwC0D0 0x17 SET_EAPD_BTLENABLE 0x02 -> value=0x0
hda-verb /dev/snd/hwC0D0 0x21 SET_EAPD_BTLENABLE 0x02 -> value=0x0
hda-verb /dev/snd/hwC0D0 0x17 SET_PIN_WIDGET_CONTROL 0x40 -> value=0x0
No audio output afterward.
speaker-test plays (no errors), but no audible output from speakers.
Expected behavior:
Internal “Speaker” sink should produce sound.
Steps to reproduce:
Boot Fedora 42 on Samsung NP960XGK with default SOF stack.
Ensure card profile: pactl set-card-profile "HiFi (HDMI1, HDMI2, HDMI3, Mic1, Mic2, Speaker)"
Set default sink to Speaker and unmute:
wpctl set-default
wpctl set-mute 0
wpctl set-volume 1.0
Confirm ALSA mixers:
amixer -c 0 set 'Auto-Mute Mode' Disabled
amixer -c 0 set 'Speaker' 100% unmute
Play test tone:
speaker-test -D default -c 2 -t sine -f 440 -l 1
Observe: no sound from internal speakers; HDMI works if selected.
Notes:
PipeWire previously showed only “Dummy Output” until card profile was reapplied; current kernels expose proper sinks.
Looks like a SOF topology/codec-init quirk for this Samsung model—likely missing EAPD/amp enable or GPIO amp control in the topology/quirks.
Willing to test patches or debug builds.

This platform also has speaker Amp. It's not own by Realtek.
Please report to Samsung or Amp vendor directly.

For anyone looking for an easy way to apply these fixes — I've packaged tested, automated install scripts for both the speaker and webcam issues on Samsung Galaxy Book4 (and others) laptops:
https://github.com/Andycodeman/samsung-galaxy-book4-linux-fixes
Speaker fix: DKMS driver for the MAX98390 I2C amplifiers (based on thesofproject/linux PR #5616). Auto-rebuilds on kernel updates and auto-removes itself when native kernel support lands.
Webcam fix: Handles IVSC module loading, Intel IPU6 camera HAL setup, v4l2loopback relay, and PipeWire device classification. Works with Firefox, Chrome, Zoom, Teams, OBS, mpv, and more.
Tested on: Samsung Galaxy Book4 Ultra, Ubuntu 24.04 LTS, kernel 6.17 (HWE). The upstream speaker PR (#5616) has also been confirmed working on the Book4 Pro, Pro 360, and Pro 16-inch by other users. If you're on a Galaxy Book5 or a different distro (Fedora, Arch, Manjaro, Debian, etc.), the fixes may still work since the underlying hardware (ALC298 + MAX98390 amps, IPU6 + OV02C10 sensor) is shared across models — but only the Ultra on Ubuntu has been directly verified. Reports from other configurations are welcome.
Note: The built-in microphones (DMIC) do not work yet on any of these models — that requires SOF driver support which is expected in kernel 7.0 (April 2026) or 7.1 (June 2026). See the repo README for details and workarounds.
